This article examines how psychometric models based on certain assumptions have come to be used counterproductively by many practitioners in ways that limit the kinds of conclusions that can be made. The general problem of the context's influence on performance is discussed, and some implications are drawn. (SLD)

Reviews the problems of benevolent misdiagnosis in the mental health professions. Misrepresentation of research or diagnosis now has the potential to affect the health care services delivered to large segments of the population. Data that will be the basis of new delivery systems must be accurate and responsible. (SLD)

Addresses persistent tensions among centralized school governance structures. Examines the literature's claims for devolution's positive benefits and shortcomings and proposes more realistic expectations. Discusses the relationship between devolution and improved teaching and learning. Reconceptualizes devolution and proposes a preliminary…

Disagrees with research showing that socioeconomic status has little impact on parental involvement in children's education. From the author's own experience, working-class parents are as concerned as affluent ones about children's progress, but have less energy/time for participation. In other research, a new assessment instrument may help…

Examines the research of Morgan, Bonamo, and Travis (1995) to detect the effects of recasted error correction on children's emerging grammar. Notes that regression procedures used by Morgan and others could not discriminate between the data generated by models in which recasts totally determined grammatical learning, supplemented other learning,…

The failure of Bohannon, Padgett, Nelson, and Mark's (1996) time-series analysis to distinguish among varying models of recast function is shown to be attributable to confounding of parameters and idiosyncratic assumptions adopted in generating simulated data from these models. (MDM)

From perspective of a psycholinguist, discusses three leading questions that have arisen from foundational, descriptive second-language-acquisiton studies: Why are certain L2 constructions learnable and others not?; In considering input requirements, is it fair to say that adult learners can take advantage of metalinguistic information about the…

Research on intergenerational continuities should consider: (1) both sides of the family; (2) the effect of change on continuities; (3) discontinuities; (4) societal and family influences; (5) variations in the meaning of traits; (6) misleading differences; (7) risks derived from personal characteristics and experiences; (8) identification of…

Two researchers who re-examined a North Carolina district's exemplary SAT performance discovered that this district's gains paralleled those in the rest of the state. The dropout rate also remained high. Most investigations of music, art, and academic learning show positive correlations, but no causal effects. (MLH)

Reviews 1980-95 research exploring the relationship between principal leadership and student achievement. Principals exercise a measurable, but indirect, influence on school effectiveness and student achievement via vision, mission, and goals. Previously described discrepancies may be attributable to researchers' conceptual and methodological…

This article comments on results of a study (EC 629 869) on the reliability of the Modified Checklist for Autism in Toddlers (M-CHAT), a early detection screening test. It discusses concerns relating to clinic vs. population samples, data analysis, use of a parent questionnaire only to identify autism, and the age of screening. (Contains…

This article responds to comments (EC 629 869-70) on a study on the reliability of the Modified Checklist for Autism in Toddlers (M-CHAT), a early detection screening test. It addresses concerns relating to clinic vs. population samples, data analysis, use of a parent questionnaire only to identify autism, and the age of screening. (Contains 6…

Research on childhood disability views disabled children as passive and dependent and excludes the voice of disabled children themselves. Because research has been preoccupied with impairment, vulnerability, and service usage, it has concealed disabled children's role as social actors. New approaches to disability and to childhood are needed to…

Argues for the use of autobiography paired with radical doubt as a strategy to arrive at intersubjectivity, thereby avoiding false claims to objectivity and failure-prone inner (hyper) subjectivity. Uses this argument to introduce the contributions to the special thematic journal issue of which this paper is a part. (Contains 24 references.)…

Considers assumptions underlying design of Bussell et al.'s Nonshared Environment in Adolescent Development study. Suggests that a source of the common environment specific to this study is the effect of an individual in mutual ratings of relationship with siblings, leading to a larger common-environment effect across variables than within…
